ANNUNCIATOR.

`SPECIFICATION forming part of Letters P Application led January 1G,1886.

To all whom it may concern:

Beit known that I, CHARLEs H. DOWDEN, of Newark, in the county of Essexand State of New Jersey, have invented a new and Improved Annunciator,of which the following is a full, clear, and exact description.

This invention .relates to certain new and useful improvements inannunciators used in hotels,with burglar alarms, and other electricsignaling devices.

rlhe object of my invention is to provide a new and improved annunciatorwhich is so constructed that the signa-ls disappear automatically afterthey have been exposed to view and require no special manipulation bythe operator to remove them, but which improved ann-unciator can also beso adjusted that the signals remain visible until they are shifted atthe instrument.

The invention consists in the construction of parts and details, as willbe fully described and set forth hcreinafter,and then pointed out in theclaims.

Reference is to be had to theaecompanying drawing, forming a part ofthis specification, in which a longitudinal view of my improvedannuneiator is shown, parts being broken out and others being insection, and the electric circuits being shown.

The electro-magnet A is connected with the line-wires b and with theline-wires c, the said wires b and c being connected with the battery Dor other electric generator in the usual manner. The armature E ispivoted at one end of the magnet, and is provided at its upper end witha lug, F, having an aperture, G, through which a pin, H, passes from alever, J, pivoted on standards I on the frame K, on which the magnet Ais held. A spring-strip, L, is interposed between the armature E and anend piece of the frame K, and prevents the armature from swinging toofar from the magnet. A weight, M, is secured on one end of the lever J,and on the other end a plate or disk, N, is secured, on which a number,letter, or other sign or mark is produced. On said lever J acontact-piece, O, is secured, which when the lever is raised is inContact with the contact-piece P, connected with the wire c and held onthe annunciator, the lever atent No. 351,099, dated October 19,1886.

J being connected with the wire c', as shown. The casing is providedwith an opening, Q, through which the disk or plate N can be seen whenraised, as shown in dotted lines. The wire c is provided with aswitch,It, and pushbutton WV, and the wire I) is provided with the push-pin S.

rlhe operation is as follows: Vhen the circuit of the wire b is closedin any suitable inanner, the armature E is attracted, and, acting on thepin H, swings the disk or plate N,with the lever J, upward, so that thesaid disk can be seen through the opening Q in the easing. The diskremains raised as long as the circuit is not broken; but as such a breakis produced 6 either by releasing the push-pin or closing the door orwindow, the lever J and the disk N drop, thus requiring the attendant tonote the number or other niark on the disk as long as the said disk israised. In certain cases this is not desirable, and it is necessary thatthe disk shall remain raised until it is released byr the attendant.Vhen this is desired, the switch R is closed, and when the lever J isswung up by the closing of the line b the contact-pieces O and I) comein contact and close the circuit in the line c. The disk N remainsraised un til the switch Ris closed,oruutil the button XV isoperated,which is so constructed as to break the circuit when it ispressed. A bell on au eXtra circuit is to be connected with the battery,and connected with the line-wires in such a manner that the bell issounded when the disk N is raised.

For burglar-alarms, &e., the push-pin S is arranged to be operated by adoor,window, Ste.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent` l. The combination, with an electro-magnet andits armature having a recessed lug, of a balanced lever having asignal-disk and a pro jecting pin placed in the recess of thearmature-lug, with two separate electric wires connected with theelectro-magnet, o1" which wires one is a long circuit, including thedoors and windows, and the other a short circuit, which can be opened orclosed by a switch, and provided with a push-button and a contact-point,substantially as herein shown and described.
